METHOD FOR PRODUCING INTERMITTINGLY COLORED YARNS.

Original application filed August 29, 1923, Serial-No. 659,974. Divided and this application filed October 22, 1823. Serial No. 670,203.

This invention relates to a method for producing intermittingly colored yarn on the bobbin whereby to produce spotted or streaked color effects when knitted or woven into fabric, as a division of our pending application, Serial Number 659,974 filed August 29, 1923.

The main object is to provide a more expeditious method of producing these spotted in or streaked efiects by dipping a limited portion such as one end or both ends of a bulk winding or bobbin of the yarn into a suitable coloring matter.

The drawing represents diagrammatically, an apparatus for carrying outthe process and consists of a vat -1-- containing a body of liquid colorin matter 2- for receiving one end or bot ends of a wound bulk or bobbin -3-' of yarn in such mannor as to color or die a limited portion of the bulk.

That is, the process consists in winding a considerable quantity of yarn upon any suitable support around and lengthwise of a common axis so as to produce a multiplicity of layers of yarn one upon the other and then immersing a limited portion such as one end or both ends of the wound bulk intoa liquid die or coloring matter, whereby when the yarn is unwound and knitted or woven into a fabric, the colored portions of the yarn will appear in spots or streaks as distinguished from the uncolored portions.

What we claim is:

1. The herein described method of producing i'ntermittingly colored yarn consisting in winding the yarn upon a bobbin so as to form a multiplicity of layers, and dipping relatively small portions only of the wound yarn upon the bobbin into a coloring liquid so as to leave the remaining portions of the yarn uncolored.

2. The herein described method of producing intermittingly colored yarn in which the yarn is wound upon a core so as to form a multiplicity of layers around the axis of the core, dipping a portion of the wound body of yarn extending from the core to the periphery of said body into a coloring liquid so as to color a portion of each layer on of the yarn.

In witness whereof we have hereunto set our hands this 13th day of October, 1923.

JAMES S; JOHNSTON. MORGAN I M. HOGAN.
